Spruce mycorrhizac and heart rot incidence caused by Fomes annosus in southwestern Germany. Naturally occurring spruce mycorrhizac on calcareous soils of southwestern Germany were investigated and classified. These soils are characterized by a relatively high incidence of heart rot caused by Fomes annosus . On comparable sites stand history (former woodlands versus former sheep pastures), though influencing heart rot incidence, had no effect on the overall distribution of mycorrhizal types. The occurrence of rare types, however, varied between sites with different stand history. For all mycorrhizal types found, isolation of the fungal symbiont was attempted. Where isolation was successful, the isolates showed no antibiotic activity against Fomes annosus .
